http://mashable.com/2015/03/31/rangers-protect-last-northern-white-rhinos/ There is only one northern white male rhinoceros left on the planet. Its home is 200km north of Nairobi in Kenya, at Ol Pejeta Conservancy. Joining Sudan, the male, are two female northern white rhinos. Together, they are three of the last five remaining northern white rhinos in the world. The subspecies are on the verge of extinction, suffering greatly since poaching surged in the 1960s. According to The Guardian, a rhino's horn can sell at prices upward of $75,000 per kilo (2.2 US pounds), leaving them under great threat.
